LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 779,690, dated January 10, 1905.

Application filed July 14, 1904. Serial No. 216,508.

To @ZZ whom, it 771/607/ concern:

Be it known that I, JOSEPH V. CLARK, a citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio,have invented certain new and useful Improvements in Lubricating Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and p use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in an oil lubricating device designed and constructed with a view of utilizing the condensation of steam to force the oil contained in the reservoir into the steam-line supplying the steam-chest and cylinder on the engine.

In the accompanying drawings, forming a part of this specification, I have illustrated my invention by two views, in which- Figure 1 is a verticall exterior view of my improved lubricator; and Fig. 2 is avertical sectional view of the head portion of my lubricator, showing the passage-ways and communicating chambers formed therein.

Like numerals of reference designate like parts throughout both views, in which- The numeral 1 represents the oil-reservoir, and 2 is an indicator-glass attached to the side and communicating with the interior of said oil-reservoir. 3 is a drain-valve in the bottom of the reservoir. Removably connected to said oil-reservoir is the head portion 4 of my lubricating device, in which are formed a number of communicating passageways for conducting the lubricant therethrough and thence into the steam-line supplying the valves on the engine. The first of these passage-ways 5 is formed in the neck of the head portion and constitutes an oil-chamber from which the lubricant may be diverted in two different and distinct directions through said head. The first or main iiow of the lubricant is through a communicating channel 6 or sight-feed line formed in an extension part 7, the iiow being regulated bya valve-stem 8,

entering the neck portion through the chamber 5 at a point directly opposite the inner end of said channel 6. The lubricant after iiowing or being forced through said channel passes upward through. a jet 9, seated over the outer end of said channel 6, and thence through the sight-glass 10, seated between said extension part 7 and a condensing-head 11,formed integral with a curved arm 12. The steam condensing in this head 11 lills the sight-glass 10, and the entire body of oil being forced directly against the jet 9 prevents the latter from clogging and insures a constant flow through said jet. As the oil passes through the body of water contained in said sight-glass and condensing-head and reaches the curved channel 13 it readily iiows down the incline formed by the curved arm and is there caught up by the steam entering said head portion through the straightway passage 14 and from there carried to any point on the engine to be lubricated.

Formed in the upper portion of the head directly over the chamber 5 and divided therefrom by a bridge-wall 15 is a steamchamber 16, communicating with the straightway passage 14 and curved channel 13. Connected to the upper end of this chamber 16 is a condensing-tube 17, which passes down through the bridge 15, thence through the oil-chamber 5, where it enters the oil-reservoir 1 and extends down nearly to the bottom thereof.

Connected to the top of the head portion is a nipple 18, engaging with the top of the condensing-tube 17 and held in position by a packing-nut 19.

Leading from the straightway passage 14 through the bridge-wall 15 is a by-path running parallel with said bridge-wall and communicating with the oil-chamber 5. This bypath affords an emergency-line for the lubricant in case anything should go wrong with the sight-feed line.

A controlling valve stem 21 enters the straightway passage 14 at a point directly opposite the by-path 20, having its seat in the same.

In lilling the reservoir 1 oil is introduced through the plugI 22, formed in the head portion.

In the operation of my improved lubricating device the reservoir is lirst lilled with oil. The straightway passage 141 and nipple 18y being connected with the steam-line and the valve 8 being open, the condensation of steam in the tube 17 by the weight of gravity over and above the equalization of boiler-pressure forces the oil contained in the reservoir through the-channel 6 up through the jet 9, where it rises to the top of the water contained in the sight-glass and condensing-head and is then carried ofi through the curved channel 13 into the chamber 16, where it mixes with the steam and is then carried to any point on the engine to be lubricated. Should the channel 6 or jet become clogged with any foreign mattei', then without interfering with the supply of lubricant to the engine the valve 21 is opened, and immediately by the same method as is employed in forcing the oil through the sight-feed line the lubricant will be forced into the straightway passage 14 direct through the by-path 2O and there be caught up by the steam and Acarried to the valve of the engine. The steam surrounding the tube 17 as it passes through the chamber 16 will keep the condensation of steam therein in a heated state, and as this warm water passes through the oil-chamber 5 and into the reservoir itserves to retain the oil in a workable or liquid state, thus preventing freezing or thickening of the same. By this system of preheating the oil contained in my lubricator l am able to use the heaviest and thickest of oils as lubricants, as they become thin and easily introduced through the valves and passage-ways and into the steam-line under the method employed in my device.

My lubricator is applicable to any variety of engine utilizing steam and may be located at any desired and convenient point either on the engine or at a reasonable distance therefrom, it being one of the features of my invention that the reservoir may be detached from the head portion and a larger supplytank be used, thus avoiding the necessity of frequent refilling.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is#

1. In an oil lubricating device, the combination with an oil-reservoir, of a detachable head portion provided with an oil-chamber, an outwardly-extended portion having a channel therein in communication with the oilchamber, and having a by-path communicating with the upper portion of said oil-chamber, said head having a bridge-wall formed therein, and a steam-chamber disposed above the same adapted to communicate with said by-path, a curved member formed integral with the upper portion of the head having a passage therethrough and a condensing-head formed at the end thereof, means connecting the condensing-head with the outwardly-projecting portion formed upon the head at the lower end thereof and in communication with the chan nel of the same, and condensing means adapted to communicate with the steam-line and extending through the bridge-wall of the head into the oil-reservoir, substantially as described.

2. In an oil lubricating device of the type set forth, the combination with an oil-reservoir, of steam-condensing means adapted to communicate with a steam-line extending into said reservoir, a detachable head portion mounted upon the reservoir provided with an oil-chamber, and a steam-chamber arranged above the same, outwardly-projecting integral members having channels in communication with the oil and steam chambers, means connecting said last-named members forming a sight-feed line therewith, said head portion being further providedv with a by-path leading from the Lipper portion of the oil-chamber and adapted to communicate with the steam-chamber at the opposite side thereof from the sight-feed line, substantially as described.

3. In a device of the character set forth, the combination with an oil-reservoir of a detachable head member provided with oil and steam chambers, a sight-feed line in communication with said chambers, means for feeding directly to the steam-chamber from the oil-chamber and steam-condensing means extending through the head portion and into the reservoir. substantially as described.

4. In a device of the character set forth, the combination with an oil-reservoir, of a detachable head portion, provided with an oil and steam chamber, a sight-feed line in communication with said chambers, said head being provided with an outwardly-extended portion having a straightway passage therein in communication with the steam-chamber and being further provided with a by-path adapted to communicate with the oil-chamber and with said straightway passage, and steam-condensing' means enteringsaid oil-reservoir, substantially as described.

In testimony whereof I afix my signature in presence of two witnesses.
